Specification of Letters Patent.

Patented Dec. 24, 1907.

Application filed May 2-1906. Serial No- 314,789.

To all whom it may concern:

Be it known that we, HENRI MARIE PHILIPPE CATOIRE, a Russian subject,and JOSEPH AUeUsTIN MARIE IVIARRET, a citizen of the French Republic,both of 10 and 12 Rue des Ardennes, in the city of Paris, Republic ofFrance, manufacturers of pasteboard arti cles, have invented anApparatus for the Manufacture of Pasteboard Boxes by Punching, of whichthe following is a full, clear, and exact description.

Up to the present the manufacture of pasteboard boxes in one or severalpieces has been effected by means of a metal disk divided into a certainnumber of sectors which, under pressure of a wedge placed in the ,centerof the disk, are forced into the body or into the cover of the box so asto form their circular rims and also the ledge which receives the cover.This process is not only very slow but it has also the disadvantage ofleaving marks on the constitutive parts of the box, the pasteboard notbeing pushed into the intervals formed by the separation of the sectors.

By our invention we form the circular rims of the box and also the ledgewhich receives the cover without'leaving any mark on the body of the boxor on the cover.

The invention is essentially characterized by the employment of a moldmade in a single piece, so that the box will have no creases or trace ofmanufacture.

The invention also consists in the particular construction andarrangement of parts as hereinafter described and pointed out in theclaims.

The accompanying drawing shows an apparatus by which the presentinvention may be carried out.

Figure 1 is a box made by the present mode of manufacture. Fig. 2 is anelevation of the metal plate on which is fixed the mandrel carrying anindia rubber disk. Fig. 3 is a corresponding plan. Fig. 4 is a sectionof the mold showing the profile of the box to be stamped. Fig. 5 is acorresponding plan. Fig. 6 represents the mandrel which compresses theindia rubber disk. Fig. 7 shows in section the pasteboard capsuleforming the body or the cover of the box. Fig. 8 shows the diflerentparts of the apparatus before the compression has begun. Fig. 9 showsthe same apparatus when the india rubber disk has been compressed andthe box stamped.

As may be seen in the drawing this apparatus is composed of an ironplate a on which is fixed a metallic mandrel b of proper height. Thismandrel b carries on its upper end a disk 0 composed of india rubber orany other compressible matter.

A hollow metal mold d presenting on its inner part the exact profile ofthe box to be made may be fixed on the plate a by means of two lugs 6cast on the mold and arranged so as to engage two lips f fixed on theplate a.

Another mandrel g, the lower part of which may be flat, concave orconvex according to the kind of box to be made, can enter the hollowmold (i, so as to compress, by means of power brought to bear on theupper part of this mandrel, the india rubber disk 0.

Letters, drawings, monograms, etc. may be engraved on the lower end ofthe mandrel g. I

The diameter of the mandrel 9 should be equal to the diameter of therims of the body or the cover of the box.

The following is the process of stamping with the apparatus arranged asdescribed.

The two parts of the box having been previously made in the form ofcapsules h by an ordinary punching machine one of those capsules, forinstance the one intended to form the body of the box, is placed on theindia rubber disk 0 as shown in Fig. 8 of the drawing. The mold d whichis provided with banks or shoulders for the purpose of forming the lowerrim 4) and the ledge of the box is then placed on the capsule h andsecured to the plate a by means of lugs e which fit under the lips f.The mandrel g is then inserted into the upper part of the hollow mold dand, by means of pressure brought to bear on said mandrel, the indiarubber disk 0 is compressed. In expanding the india rubber' ushes thepasteboard in all directions and orces the capsule h to assume the exactform of the mold d. The cover of the box is made in the same way, theshape of the mold being, however, changed so as to form only the upperrim z" of the cover.

From what has been said it may be seen that the apparatus permits ofstamping out pasteboard boxes without making any marks upon them.

This apparatus also permits of producing in rilievo, either on thebottom or on the cover of the box, letters, monograms, drawings, etc.

The expansion of the india rubber forces the pasteboard into all theparts of the mold, Which is not done by any other process employed up tothe present, all of them leaving marks on the pasteboard, caused by thespreading out of the sectors, as has already been said.

Naturally the capsules it should contain the quantity of pasteboardnecessary to allow of the formation of the rims i and 'i and the ledgeof the box.

The mandrel 9 may be mounted on any machine capable of producing thepressure necessary for the compression of the india rubber disk 0.

The above arrangements are described only as an example; the forms,dimensions and details may be varied according to circumstances Withoutmodifying the principle of the invention.

Claims.

1. An apparatus for forming pasteboard boxes, consisting of a base, amandrel on the base, a disk of compressible material on the mandrel, amold formed of a single piece and removably secured to the base With themandrel projecting into the same, the face of the mold being of thecontour of the box to be formed, and a second mandrel adapted to enterthe mold and compress the disk on the first named mandrel.

2. An apparatus for forming pasteboard boxes, comprising a mold formedof a single piece and having the contour of the box to be formed, anelastic mandrel projecting into one end of the mold, and a rigid mandreladapted to enter the other end of the mold.

3. In an apparatus for forming pasteboard boxes, a base provided withlips, a mandrel carried by the base, and a mold on the base and intoWhich projects the mandrel, said mold being provided With lugs forengaging the lips of the base to secure the mold thereto.

The foregoing specification of our process of manufacture of pasteboardboxes by punching signed by us this 20th day of April, 1906.
